Workshop on drought and remote sensing
11-15 November 2013, Brdo, Slovenia
WORKSHOP REPORT
1. Introduction
In the framework of the IPA/2012/290552 multi-beneficiary project “Building Resilience to Disasters
in Western Balkans and Turkey”, a workshop on application of remote sensing data for drought
monitoring was organized on 11-15 November 2013 in Brdo, Slovenia. The overall objective of the
project is to reduce vulnerability of IPA beneficiary countries to disasters caused by natural
hazards in line with the Hyogo Framework for Action and increase their resilience to climate
change. The direct beneficiaries are the national authorities in charge for the disaster risk reduction
and disaster risk management and the National Meteorological and Hydrological Services
(NMHSs) of Albania, Bosnia and Herzegovina, Croatia, Montenegro, Serbia, Kosovo*, the former
Yugoslav Republic of Macedonia and Turkey. The project activities are grouped in eight tasks, of
which four are implemented under WMO management. Among others, major efforts will be
undertaken to strengthen the capacities of the NMHSs regarding hazard analysis and mapping.
Training workshop on application of remote sensing data for drought monitoring with emphasis on
EUMETSAT LSA SAF products was organized by Slovenian Environment Agency/DMCSEE with
the support from the project. The workshop was participated by 6 experts from project beneficiaries
(participant list is attached as Annex II). Participants are experts in field of drought analyzing and
monitoring from national meteorological services of SE Europe.
Vegetation parameters and evapotranspiration, calculated from measurements of the
geostationary satellite Meteosat and prepared in scope of Land Surface Analysis Satellite
Application Facility (LSA SAF) were presented. The operational system of monitoring and
determining drought at Slovenian Environment Agency was introduced. It is based on monitoring of
current satellite vegetation images, prepared in the frame of LSA SAF and compared with
averaged vegetation conditions calculated on the basis of archived values from the year 2006. In
the training part of the workshop, practical directions for operating with LSA SAF products, such as
data input and processing in GIS environment were given.

2. Activities
The opening session was devoted to introduction to basic properties of remote sensing data and
application of satellite measurements in meteorology. Special emphasis was devoted to
METEOSAT satellites – mainly due to the fact that METEOSAT data is already available in most of
the regional meteorological services and there are some experiences in data treatment.
Introduction to METEOSAT satellite system was given by expert in satellite meteorology Ms.
Mateja Iršič Žibert from Slovenian Environment Agency.
Following sessions were focused on Land-surface analysis satellite application facility (LSA –SAF)
developed by Institute of Meteorology and Geophysics from Portugal (IPMA). Lectures were given
by Ms. Carla Sofia Barroso from IPMA; main emphasis was given to theoretical description of
vegetation and soil temperature and to practical information on data formats etc. next session was
devoted to assessment of evapotranspiration; although limited information on ET process can be
obtained from satellites, it is still valuable source of information in combination with other datasets
(ie. Global forecast data). Lectures were given by Mr. Nicholas Ghilain from Royal Meteorological
Institute of Belgium.
Second part of the workshop was devoted to practical training. After initial lectures, Mr. Boštjan
Muri from space institute Vesolje-SI led hands-on training; the goal of this session was that
participants gain experiences in opening, visualizing and using LSA-SAF data.
3. Major issues, outcomes and problems
The participants of the workshop understood and learned importance of remote sensing data for
drought analysis. It represents valuable alternative to classical ground measurements; also more
complex and recently developed drought indicators are based on point measurements of
temperature and precipitation. Satellite measurements reveal vegetation response on conditions
and through actual impacts reveal influence of drought conditions on crops.
The tools presented and used during hands-on training were not optimal; in order to enable
participants to use data as soon as possible, a simple command-line tool was prepared to read and
reformat files with satellite measurement data. All participants were able to process sample data
and open it in desktop GIS environment where it can be visualized and/or overlayed with other
data layers.
The LSA-SAF products are suitable for operational analysis; however spatial resolution is low
(pixel size cca. 4 km for our geographical latitude) so there are limited options for their applications;
definitely they are appropriate for general overview of situation.
4. Conclusions and recommendations – round table discussion
Participants from Bulgaria see possibilities for monitoring of wheat status in combination with
other methods (ie. »GIS vesion« of the ISAREG model). It is also possible to gain additional
knowledge on crop coefficients.
In FYR Macedonia remote sensing data is not implemented. However they see potential in
tobacco fields and vineyards.
In Montenegro they already have experiences with performance of remote sensing data.
Assessment was done for whole country. For 3 agriculture areas in the country the results were
satisfactory (flat areas near rivers and coast). They recommend to select and focus

implementation of remote sensing data on relevant areas. A lot of potential is also for
monitoring danger of forest fires.
In NMHS of Serbia application of remote sensing data in agrometeorology is in development.
Data (incl. LSA SAF) is received. There is need to study previous drought periods and to create
a reference data set in order to study and define most appropriate indicators. Currently
indicators such as SPI, PDSI, Z-index and model CropSyst are implemented.
Request for LSA data – we should organize common request for study purpose.
Precipitation anomalies (station level, seasonal grids) and SPI maps are basic products for
drought monitoring in Croatia. Vulnerability map is also available. They have completed
relevant internal projects (definition of less favourable agricultural areas etc.). Forest fire index
is also used. Remote sensing data is currently used for weather forecasting, it is not archived.
SAF data is used for analysis of albedo and radiation budget. LSA SAF is currently not used,
they will explore possible applications.
In Bosnia remote sensing data is used in synoptic department. Currently they calculate
monthly drought indicators based on ground measurements. Participants from Bosnia see
potential applicability of LSA-SAF data, mainly for improvement of monthly and seasonal
analysis.
